In the Pennsylvania U.S. Senate race, Democratic State Treasurer Robert Casey Jr. leads
incumbent Republican U.S. Sen. Rick Santorum 48 - 42 percent among likely voters,
including leaners, with 5 percent for Green party candidate Carl Romanelli and 5 percent
undecided, according to a Quinnipiac University poll released today.

In a two-way matchup among registered voters, Casey leads Sen. Santorum 47 - 40
percent, with 11 percent undecided. This compares to a 52 - 34 percent Casey lead in a
June 21 poll by the independent Quinnipiac (KWIN uh-pe-ack) University.

In this latest survey, 27 percent of likely voters who name a candidate say they still
might change their mind.

By a 49 - 42 percent margin, Pennsylvania likely voters say Santorum does not
deserve to be reelected. Among registered voters who back Casey, 42 percent say their
vote is mainly against Santorum, while 50 percent say their vote is mainly for the
Democrat.

"Bob Casey's lead over Sen. Santorum has shrunk to single digits in part because
the Green Party candidate is siphoning votes from the Democratic challenger. It's not
surprising Sen. Santorum has narrowed the gap, but his bid for re-election is still in
trouble as long as almost 50 percent of the voters say he does not deserve another term,"
said Clay F. Richards, assistant director of the Quinnipiac University Polling Institute.

"Casey still has the advantage as long as Santorum's job approval is mixed and his
favorability rating remains in negative territory. But three in 10 likely voters say they
don't know enough about Casey to form an opinion, and the key to the election may well
be how those voters will swing once they get to know him. Santorum gets no help from
President Bush, whose approval rating remains near record lows," Richards added.

Pennsylvania voters disapprove 64 - 33 percent of the job President George W.
Bush is doing overall, virtually unchanged from June 21. Voters also disapprove 64 - 31
percent of his handling of the situation in Iraq and say 58 - 36 percent that going to war in
Iraq was the wrong thing to do.

From August 8 - 13, Quinnipiac University surveyed 1,384 Pennsylvania voters
with a margin of error of +/- 2.6 percentage points. The survey includes 1,011 likely
voters with a margin of error of +/- 3.1 percentage points.

The Quinnipiac University Poll, directed by Douglas Schwartz, Ph.D., conducts
public opinion surveys in Pennsylvania, New York, New Jersey, Connecticut, Florida and
the nation as a public service and for research.
